The present invention relates to new and valuable HERBICIDE herbicidescontaining mixtures of active ingredients.

It is known that benzothiadiazinone dioxides (German Laid-Openapplication No. 1,542,836) and phosphoric esters have a herbicidalaction. However, this action is not always satisfactory.

We have now found that a composition of a. a compound of the formulawhere R denotes lower alkyl of a maximum of 4 carbon atoms and R denoteshydrogen, or a salt thereof, e.g., a salt of ammonium, sodium,potassium, lithium, calcium, magnesium, ethylamine, dimethylamine,ethanolamine, diethanolamine, and dimethylethanolamine,

and b. a compound of the formula where R and R each denote lower alkyl,alkenyl, or alkynyl, Z denotes methyl, n denotes one of the integers 0,l, 2 and 3, Y denotes oxygen or sulfur, and X denotes CH O or N, has abetter herbicidal action than its individual components.

The compositions may contain one or more components of formula a and offormula b.

The ratio of the active ingredients of formula a to those of formula bmay be varied at will; it is, however, preferred to use a ratio of a bof from l to 1 3 parts by weight.

wanted plants in, for instance, the following crops:

Oryza sativa Zea mays Triticum spp. Hordeum spp. Secale cereale Thecompositions may also be used as total agents in ditches, on aquaticareas, railway tracks, barren and waste land, etc.

Glycine max. Solanum tuberosum Gossypium hirsutum Beta vulgaris. Sorghumbicolor Saccharum officinarum.

The agents have a strong herbicidal action and may therefore be used asweedkillers or for controlling the growth of unwanted plants. Whetherthe new active ingredients are used as total or selective agents dependsin essence on the amount of ingredient used per unit area.

By weeds and unwanted plant growth are meant all monocotyledonous anddicotyledonous plants which grow in loci where they are not desired.

The agents according to the invention may therefore be used forcontrolling for instance Gramineae. such as C ynodun spp. Digilaria spp.Eclzinochloa spp. Selaria spp. Panit'um spp. Alopecurus spp. Lolium spp.Sorghum spp. Agmpyron spp. Phalaris spp.

Application may be effected for instance in the form of directlysprayablesolutions, powders, suspensions, dispersions, emulsions, oildispersions, pastes, dusts, or

granules by spraying, atomizing, dusting, broadcasting or watering. Theforms of application depend entirely on the purpose for which the agentsare being used; in any case they should ensure a fine distribution ofthe active ingredient.

For the preparation of solutions, emulsions, pastes and oil dispersionsto be sprayed direct, mineral oil fractions of medium to high boilingpoint, such a kerosene or diesel oil, further coal-tar oils andoils ofvegetable or mineral origin, aliphatic, cyclic and aromatic hydrocarbonssuch as benzene, toluene, xylene, paraffin, tetrahydronaphthalene,alkylated napthalenes, methanol, ethanol, propanol, butanol, chloroform,carbon tetrachloride, cyclohexanol, cyclohexanone, chlorobenzene,isophorone, etc., and strongly polar solvents such as dimethylformamideand dimethyl sulfoxide are suitable.

Aqueous formulations may be prepared from emulsion concentrates, pastes,oil dispersions or wettable powders by adding water. To prepareemulsions, pastes and oil dispersions the ingredients as such ordissolved in an oil or solvent may be homogenized inwater by means ofwetting or dispersing agents, adherents or emulsifiers.Concentrateswhich are suitable for dilution with water may be preparedfrom active ingredient, wetting agent, adherent, emulsifying ordispersing agentand possibly solvent or oil.

Examples of surfactants are: alkali metal, alkaline earth metal andammonium salts of ligninsulfonic acid, naphthalenesulfonic acid,phenolsulfonic acids, alkyl aryl sulfonates, alkyl sulfates. and alkylsulfonates. alkali metal and alkaline earth metal salts ofdibutylnaphthalenesulfonic acid, lauryl ether sulfate, fatty alcoholsulfates, alkali metal and alkaline earth metal salts of fatty acids,salts of sulfated hexadecanols, heptadecanols, and octadecanols, saltsof sulfated fatty alcohol glycol ether, condensation products ofsulfonated naphthalene and naphthalene derivatives with formaldehyde,condensation products of naphthalene or naphthalenesulfonic acids withphenol and formaldehyde, polyoxyethylene octylphenol ethers, ethoxylatedisooctylphenol, ethoxylated octylphenol and ethoxylated nonylphenol,alkylphenol polyglycol ethers, tributylphenyl polyglycol ethers,alkylaryl polyether alcohols, isotridecyl alcohol, fatty alcoholethylene oxide condensates, ethoxylated caster oil, polyoxycthylenealkyl ethers, ethoxylated polyoxypropylene, lauryl alcohol polyglycolether acetal, sorbitol esters, lignin, sulfite waste liquors and methylcellulose.

Powders, broadcasting agents and dusts may be preparedby mixing orgrinding the active ingredients with a solid carrier.

Granules, e.g., coated, impregnated or homogeneous granules, may beprepared by bonding the active ingredients to solid carriers. Examplesof solid carriers are mineral earths such as silica gel, silica acid,silicates, talc, kaolin, Attaclay, limestone, lime, chalk, bole, loess,clay, dolomite, diatomaceous earth, calcium sulfate, magnesium sulfate,magnesium oxide, ground plastics, fertilizers such as ammonium sulfate.ammonium phosphate, ammonium nitrate, and ureas, and vegetable productssuch as grain flours, bark meal, wood meaL'and nutshell meal, cellulosicpowders, etc.

There may be added (if desired, immediately before use) to thecompositions or individual active ingredients (used singly, eitherbefore, simultaneously with and/or after the active ingredients of theinvention) oils of various types, herbicides, fungicides, nematocides,

insecticides, bactericides, trace elements, fertilizers, antifoams('e.g., silicones), growth regulators, antidotes and other herbicidallyeffective compounds such as substituted anilines, substitutedaryloxycarboxylic acids and .salts,'esters and amides thereof,substituted ethers, substituted arsonic acids and their salts, estersand amides,v substituted benzimidazoles, substituted benzisothiazoles,substituted benzothiadiazinone dioxides, substituted benzoxazines,substituted benzoxazinones, substituted benzothiadiazoles, substitutedbiurets, substituted quinolines, substituted carbamates, substitutedaliphatic carboxylic acids and their salts, esters and amides,substituted aromatic carboxylic acids and their salts, esters andamides, substituted carbamoylalkylthiolor -dithiophosphates, substitutedquinazolines, substituted cycloalkylamidocarbothiolic acids and theirsalts, esters and amides, substituted cycloalkylcarbonamidothiazoles,substituted dicarboxylic acids and their salts, esters and amidessubstituted dihydrobenzofuranyl sulfonates, substituted disulfides,substituted dipyridylium salts, substituted dithiocarbamates,substituted dithiophosphoric'acids and their salts, esters and amides,substituted ureas, substituted hexahydro-lH-carbothioates, substitutedhydantoins, substituted hydrazides, substituted hydrazonium salts,substituted isooxazole pyrimidones, substituted imidazoles, substitutedisothiazole pyrimidones, substituted ketones, substitutednaphthoquinones, substituted aliphatic nitriles, substituted aromaticnitriles, substituted oxadiazoles, substituted oxadiazinones,substituted oxadiazolidine diones, substituted oxadiazine diones,substituted phenols and their saltsand esters, substituted phosphonicacids and their salts, esters and amides, substituted phosphoniumchlorides, substituted phosphonalkylglycines, substituted phosphites,substituted phosphoric acids and their salts, esters and amides,substituted piperidines, substituted pyrazoles, substituted pyrazolealkylcarboxylic acids and their salts, esters and amides, substitutedpyrazolium salts, substituted pyrazolium alkyl sulfates, substitutedpyridazines, substituted pyridazones, substituted pyridine carboxylicacids and their salts, esters and amides, substituted pyridines,substituted pyridine carboxylates, substituted pyridinones, substitutedpyrimidines, substituted pyrimidones, substituted pyrrolidine carboxylicacid and its salts, esters and amides, substituted pyrroliclines,substituted pyrrolidones, substituted arylsulfonic acids and theirsalts, esters and amides, substituted styrenes, substitutedtetrahydrooxadiazine diones, substituted tetrahydrooxadiazole diones,substituted tetrahydromethanoindenes, substituted tetrahydrooxadiazolethiones, substituted tetrahydrodiazine thiones, substitutedtetrahydrothiadiazole diones, substituted aromatic thiocarbonylamides,substituted thiocarboxylic acids and their salts, esters and amides,substituted thiol carbamates, substituted thioureas, substitutedthiophosphoric acids and their salts, esters and amides, substitutedtriazines, substituted uracils, substituted uretidine diones.
